Sony KDL-32M3000 no picture

[deer]

Tv shows nothing on screen ( no menu - no volume bar - nothing at all )

When power button is pressed 3 seconds later the backlights come on then after another 3 seconds the backlights go out and then 4 seconds later the backlights come back on and stay on.

The main board was replaced with a board from Ebay with no change.

Please advise what would be recommended as my next step.

Thank You in advance.

First, you need to post the pictures of the backside of the TV so we can see what we are dealing with first.

At the top of the TV there is a board under a metal case, can you unscrew the case and get a picture of the board? (Once you undo the case, put the screws into the board where the case holes used to be so we can do diagnosis on it.)

OK, right near the rainbow coloured input cable from the main board (LVDS) there is a small surface mounted fuse, F1. Please check the resistance of this fuse with a digital multimeter.

At the F1 fuse there is a resistance reading of 303 kohms

I have the same problem, Sony KDL-32M4000
I replaced the fuse and now the large chip on the T-CON board is getting very hot and the screen shows this.

How about when you put time and money into a TV and it needs a new screen.
The customer says you didn't fix it, so I don't owe you anything.
